Since you became a lawful permanent resident, have you called yourself a "nonresident alien" on a Federal, state, or local tax return, or decided not to file a tax return because you considered yourself to be a nonresident?
I answered “yes.” But now I have realized that I worked in my hometown for four months in 2017 and paid taxes there. My income was quite small — about $8,000.
So what should I do now? Should I still say “yes” during the interview? And how can I submit a U.S. tax return for 2017 now?
Thank you so much for your help!
